14 DAY TRIAL // Professor Erik Asphaug from the University of California at Santa Cruz is convinced that, many years ago, two moons used to orbit planet Earth.
One of these moons was considerably smaller than the other. The Telegraph reports that, according to Professor Erik Asphaug's estimates, its size was about one-thirtieth of that of the moon now towering over our heads.
This fairly small moon got to orbit our planet for merely a few million years before colliding with the bigger one. The collision led to the formation of the moon as we know it.
“The second moon would have lasted for only a few million years; then it would have collided with the moon to leave the one large body we see today.”
“It would have orbited Earth at the same speed and distance and just got slowly sucked in until they hit and then coalesced,” Professor Erik Asphaug explains.
The researcher maintains that the mountain-like structures we can now observe on the surface of our planet's satellite were created when these two moons collided.
